March 10, 1930.Serial N o. 434,825.

My invention relates to gain fixtures for poles such as are used for theservice of telegraph, telephone, electric light, tc., and has for itsobject to avoid boring a hole through the pole for a securing bolt, andalso to provide for ready adjustments of the fixture so that thecross-arm supported thereby may be in proper alinement.

In the accompaying drawing which is to be read as a part of thedescription which follows Figure 1 is a front elevation of a cross-armsecured in position to a pole by my improved fixture- Figure 2 is a sideelevation- Figure 3 is a section at the line 3 3 of Figure 1- Figure 4is a view similar to Figure 1 With the cross-arm removed, and

n Figure 5 is a detail rear view of the fixture with the cross-arm inplace.

Similar numerals of reference denote like parts in the several figuresof the drawing.

1n securing a fixture of this sort to a pole, a hole is usually boredentirely through the pole to accommodate the bolt that supports thefixture, but it has been found that Water will get into the bore, thebolt Will rust, and rotting of the pole will ensue, which not onlyweakens the pole but causes the Wall of the bore to no longer afford acomparatively close fitting support for the bolt, and the latter willconsequently sag and Wabble, thereby rendering the fixture inefiicient.

In my improvement, the means for supporting the fixture consists of aheavy metal band or strap 1 that embraces the pole 2 and ext-ends partWay around the latter, the ends of the band being pierced as at 3, toaccommodate large lag screws 4 that are driven, preferably at an angleWithin the pole, as shown at Figure 3, and this band is curved and isspaced at its central portion from the pole as shown at 5.

6 is the gain fixture Whose sides 7 contact the pole and are cut awaymidway of their length to form recesses 8 that embrace the upper andlower edges of the band 1, Which thus affords a support for the fixture,and the latter can be shifted along the curved band, for plained.

9 is a bolt whose head 10 is in the rear of the band l Within the space5, the bolt being inserted through a hole in the band.

11 is the cross-arm which is seated to the fixture between lugs 12 thatextend from the corners of said fixture, and the bolt 9 extends throughan elongated slot 13 in the fixture and through the cross-arm, and theouter end of the bolt is threaded and extends beyond said arm, a nut14E, With an interposed Washer 15, being driven on said end to hold thearm firmly in position. i

1n installing fixtures of this sort, it frequently happens that thecross-arm does not aline properly With other arms on the same pole orwith the similar arms on precedingk or succeeding poles, either becausethe band is not accurately positioned on the pole, o-r because thefixture itself is not suitably adjusted along the curved band, and insuch an instance, the nut is relaxed and the fixture slid along the bandin either direction, as the occasion may demand, until the arm assumesproper position, and the nut is then tightened.

All poles are subjected, as a rule, to a liquid treatment that acts as apreservative and extends a certain distance Within the poles, and thelag screws, While they do not penetrate beyond the treatment,nevertheless could be safely used With untreated poles, since suchscrews are taper threaded and effectually plug the openings which theymake.

TNhat is claimed is 1. A. gain fixture for poles, curved bandextendingpartWay around the pole and secured thereto by lag screws driven throughthe ends of the band into the pole, said band being from the pole, afixture having an elongated slot in its face and Whose sides contact thepole and are adjustably supportedV on said comprising a 9 band, across-arm seated to said fixture, a

bolt extending from said band through said slot and cross-arm, and a nutdriven on the end of said bolt.

2. A gain fixture for poles, comprising a curved band secured to thepole and spaced the purposepresently to be Yex-V spaced at its centralportion` therefrom at its central portion, a` ixture sldably supportedon said band and having its sides contacting the pole, a cross-armSeated to Said xture, a bolt extending from said band through saidiXture and cross-arm, and a nut driven on the end ofthe bolt againstsaid arm.-

3. A gain fixture for poles, comprisingea Curved band secured .to thepole and spaced therefrom .atiits` Central portion, A:i fixtures'li'diibly supported by said bend cand having its sides contacting thepole, a. cross-arm supported by said ixture, and means for securing saidfixture and cross-ar1n directly to said band.

In' testimony whereof I .ax my signatute hereto.
